New info on how VW, Porsche, Audi V6 TDI engine cheat works

The German newspaper Bild am Sonntag is reporting that US investigators have found three pieces of software that work in concert to turn off the emissions control equipment in certain diesel models after a set period of time. The engine in question, the 3.0-liter TDI turbodiesel, was found in certain Volkswagen Touareg, Audi Q7, and Porsche Cayenne models – the sale of which was suspended in the US late last year. Since most emissions compliance testing takes around 20 minutes, the software in the three VW Group models shuts off the emissions control equipment after 22 minutes, a straightforward end run around the testing. Remember that the 3.0-liter TDI engines aren't included in the big buyback and recall program announced for the smaller 2.0-liter, four-cylinder TDI engines. The 3.0-liter engines will likely get their own program, but we don't know when to expect it or exactly what it will look like. Last month, California rejected a proposed fix for the larger TDI engines, and VW went back to the drawing board. Since the company is unlikely to create two fixes, one for California and one for the rest of the nation, the company can't really proceed until they figure out a solution California will accept. The EPA hasn't officially commented on the report, and we don't know how Bild am Sonntag came across the information, but we'll be closely watching what emerges after this report. Related Video:

Porsche reveals first Macan driving and manufacturing footage

One of the more anticipated offerings of the upcoming year, Porsche's sporty baby Cayenne, the 2015 Macan, has already earned nods of approval from a number of Autoblog staffers. We named it one of the top five debuts at last month's LA Auto Show, citing its 400-horsepower turbocharged engine and other sporty bits as good reasons to get excited about Stuttgart's latest.
And while our first test may be many months away, we're keeping our ears to the ground for any information on Porsche's compact crossover. We're especially keen on stuff like this - our first look at the new model in motion and undergoing assembly at its Leipzig plant. Both are shorter videos, and while there's little of the glorious engine noise we've already been teased with, the videos do offer a great look at the handsome Macan on the road, as well as glimpse at Porsche's state-of-the-art manufacturing operations.
Scope out the videos below and let us know what you think.

2015 Porsche Cayenne spotted with facelift

Although it's only been a few years since the current Porsche Cayenne was introduced, Porsche seems to be working on a midcycle update for its big SUV possibly in time to welcome the smaller Macan. As seen in these recent spy shots, it looks like the Cayenne will be getting a minor face- and butt-lift, but it's hard to say what other changes are in store or when the updated model will hit showrooms.
Up front, expect the Cayenne's new face to resemble what was just revealed on the 2014 Panamera, and we could also see this SUV using some of the new engines introduced on the Panamera including the 3.0-liter twin-turbo V6 or maybe even the E-Hybrid model. We're guessing that the new Cayenne could debut sometime next year likely for the 2015 model year. In the meantime, check out the gallery of spy shots above.
